The Arduino UNO R4 Minima is the first UNO board to feature a 32-bit microcontroller. It features a RA4M1 series microcontroller from Renesas (R7FA4M1AB3CFM), which embeds a 48 MHz Arm® Cortex®-M4 microprocessor. The UNO R4 Minima’s memory is larger than its predecessors, with 256kB flash, 32kB SRAM and 8kB data memory (EEPROM). The UNO R4 Minima board’s operating voltage is 5VDC, making it hardware compatible with UNO form factor accessories with the same operating voltage. Shields designed for previous UNO revisions are therefore safe to use with this board but are not guaranteed to be software compatible due to the change of microcontroller.
